138514 ÷ 99 
The aim is to understand the frequency of 99 in 138514.

Step 1:
The number 99 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 99

Step 2:
If we divide 13 by 99, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 99

Moving on to step 3:
138 divided by 99 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 39 after subtracting 99 from 138.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 99

Advancing to step 4:
99 can be fit into 395 3 times, resulting in a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 98 after subtracting 297 from 395.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 99

Step 5:
99 goes into 981 9 times with a remainder of 90.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
The remainder is 90 after subtracting 891 from 981.
Grab the next digit (4) from the dividend, add it to 90, then carry on: 904 / 99

Advancing to step 6:
When dividing 904 by 99, we get 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 1399.0
If we take 891 away from 904, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
The number 99 fits into 130 1 times, leaving a remainder of 31.
The next digit of our result is 1. 
Result so far: 1399.1
If we subtract 99 from 130, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 8:
The number 99 fits into 310 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1399.13
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
The number 99 fits into 130 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1399.131
Subtract 99 from 130 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 10:
If we divide 310 by 99, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 1399.1313
If we take 297 away from 310, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
The number 99 fits into 130 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 1399.13131
Subtract 99 from 130 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 12:
When dividing 310 by 99, we get 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 1399.131313
Deduct 297 from 310 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
The number 99 fits into 130 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1399.1313131
Deduct 99 from 130 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
The number 99 fits into 310 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 1399.13131313
Subtracting 297 from 310 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 1399.13131313, and the remainder is 1.3e-08.
